Near the end of last week's Sencha Touch 2 beta release blog post there was an appeal to the community to help raise awareness of a nasty flashing issue with Android 4.x phones. Every time you tried to use an animation on a web page the browser would flash, wait a bit, then finally perform the animation.

We filed a ticket on this about a week ago and thanks to your help (over 300 of you starred the issue), got a prompt response from the Android team with a fix for the flashing issue.

Getting it Right

However, that's only half the story. While the ugly flash is gone, animation performance on Android 4.x phones is still unacceptable. As it stands a 2 year old device running Android 2.x easily outruns the top of the range devices today running 4.x.

We really want to have excellent support for all Android devices. While 4.x accounts for only 1% of all Android phones today, that number is only going to go up. And when it does, we want to be ready to ship fast, fluid, beautiful apps onto it.

So we've created a new ticket with reduced, reproducible test cases and filed it to the bug tracker. We'll continue to give the Android team as much support as we can in order to resolve this quickly, but once again we'll need your help.
